auto close not working on dropdown

[amoldorkar-ezest]

here is my code

<div class="btn-group user-role" role="group" dropdown [autoClose]="'always'">
    <button id="dropUserRole" type="button" dropdownToggle class="btn btn-secondary dropdown-toggle" data-toggle="dropdown" aria-haspopup="true" aria-expanded="false">
        Super Admin
    </button>
    <div class="dropdown-menu" aria-labelledby="dropUserRole" dropdownMenu>
        <a class="dropdown-item" href="#">Dropdown link</a>
        <a class="dropdown-item" href="#">Dropdown link</a>
    </div>
</div>

I think always is the default behaviour, so if you remove [autoClose]="'always'" entirely, you should get the behaviour that you want.
